problem using <execution> on linux

I have a problem using <execution> on Linux.

Here is the Linux compile

icpc -O3 -parallel -fopenmp -std=c++20 -xhost ch3804.cxx -o ch3804.out
ch3804.cxx(1): catastrophic error: cannot open source file "execution"
#include <execution>

compilation aborted for ch3804.cxx (code 4)

The same program compiles and runs to completion on Windows.

Here are the first few lines of the code.

#include <execution>
#include <iostream>
#include <algorithm>
#include <array>
#include <random>
#include <string>
#include <chrono>

using namespace std;

I tried googling but could not find anything useful.

I tried attaching the complete program but got this message.

The attachment's ch3804.cxx content type (text/plain) does not match its file extension and has been removed.

Any thoughts?

I've written some examples to compare user sorting, with stl serial sorting and stl parallel sorting.

Hi Ian,


You are getting an error since <execution> is currently only available on msvc. Intel c++ compilers havent implemented <execution>.

But intel does offer its own implementation for parallelism which is DPC++. If you are interested, please refer Data Parallel C++ Documentation — oneAPI DPC++ Compiler documentation (intel.github.io) for getting started with dpc++.
